Alexander Popov used a coherer attached to a vertical wire designed to record atmospheric disturbances. One of the early experimenters with electricity, magnetism and eventually radio waves. He's not me, even if I've been known to Popov now and again... But thank ye for the goodly time.

Oops- gotta get back on topic...

Here's one I bandy about when it looks like my adversary is acting obsequiously:

I know on this thread I will just sit back and enjoy.
You are both too good for me. I guess I knew about
Popov but did not make the connection and as for the
valid Latin sentence, I did not see the sentence in
the column form: Sator arepo tenet opera rotas.
But I do now. I am borrowing sluggo's term: I am
somewhat sluggish. But I know I had better come up
with a new one for this: perhaps something connected
with sheep???

As mentioned elsewhere the only palindrome I was
personally connected to was a friend whose last
name was Noxon. I do need to work on them. Never
really had much to do with them, but I enjoy this
thread, and look for more "inspiration" from you two.

You are really good. Do you stay up nights figuring
these out???? All those names, would drive me crazy,
(crazier). If I start with palindromes I probably will never
stop: sort of like crosswords, or potato chips.
I have, however, bookmarked that site. Thanks.
